een difficult to examine whether these signals correlate with per<strong>for</strong>mance because monkeys are<br />

typically overtrained to per<strong>for</strong>m at high levels, resulting in very few error trials. To address this<br />

issue, we examined hippocampal activity as two monkeys per<strong>for</strong>med the Visual Preferential<br />

Looking Task (VPLT). This task relies on the monkey‟s innate preference <strong>for</strong> novelty, and<br />

there<strong>for</strong>e requires no specific training. Additionally, this task elicits variations in per<strong>for</strong>mance<br />

that allow <strong>for</strong> an examination of the relationship between trial-to-trial fluctuations in recognition<br />

memory and neural signals recorded in the hippocampus.<br />

Monkeys freely viewed large stimuli (11°), which were presented twice each and remained on<br />

the screen as long as the monkey continued to look at them, up to a maximum looking time of 5<br />

seconds. Successful recognition is evidenced by a decrease in looking time <strong>for</strong> the repeated<br />

stimulus presentation, i.e., a preference <strong>for</strong> novelty. Overall, both monkeys demonstrated<br />

significant recognition memory (p
